Was wondering if anyone worked with a traditional (not POD) printer which also prints postcards? I'm looking for someone inexpensive (priority) and of "medium or higher" quality (doesn't have to be gorgeous) for a summer project. I want to go with traditional publishing to keep bulk costs down to as very little as possible.

Ah hah, coincidentally we have similar plans for our publications this summer. My brother Markku tells me that www.printplace.com is his favourite as regards postcard printing; this has nothing to do with printing experience at this point, though, he just likes how they have clear and professional pricing information on their pages. Apparently we're going to try them out for our own project.

Just wanted to peek back into this thread and report on my experience with PS Print, which I decided on over UPrint (for better price break on the flyers, when I jacked the quantity up to their minimum, which is 2500). I got both my 4x6's and my bookmarks in a week from the day of ordering. Print and cutting quality is dead on. Only issue at all is that the flyers at the top of the box had a little squishing at the edges, from bouncing around a little.

Point is, if one were to act fairly quickly, one could place an order today and still have 'em in time for Gen Con.

We've used Print Place a couple times before. Not for post cards but rather for various sized fliers. If you ever print onto their 70lb uncoated text stock it'll come out splotchy and ugly because they seem to be using a very cheap brand of 70lb stock. But anything printed onto their coated stocks comes out looking good.
